Jackman’s large flowered Clematis is one of the hardiest varieties. It’s a reliable bloomer that grows back every year even after the coldest winters. The eye catching dark purple flowers that with cream anther will bring to life a cascade capable of covering large bare area and provide shade to a patio. Pruning Group: 3.
Group 1 – Flowers only on old wood (previous year). Prune after spring flowering.
Group 2 – Flowers on both old and new wood. Little pruning should be done for woody-stemmed members of this Group. If cut to the ground or pruned in fall or spring, flowering will be reduced or delayed, but not prevented.
Group 3 – Flowers only on new wood. Can be cut to the ground in fall or spring.
